Abstract: ABSTRACT OF THE DISCLOSURE     A method and an apparatus, in a telecommunication sys-tem for transmission of digital information in duplex over a signal conductor pair for automatically adjusting a balance filter included in a hybrid coupler circuit with the aid of adaptive echo cancellation so that the local data trans-mitter does not disturb the local data reception, without utilizing any particular testing procedure in initiating the adaptive echo cancellation.  A control signal is formed which with the help of which the correction unit, is caused to generate signals for rapid updating of the balance filter parameters, in spite of the fact that knowledge is locking in the initiation instant concerning the valve of the sig-nal transmitted from the remote end to the apparatus, and that no counteraction between level correction and filter adaption is obtained.  The apparatus includes a quantizer in which a sampled, received signal is quantized and an estimated signal of data sent from the remote end is obtain-ed.  The estimated signal is multiplied by a reference sig-nal from a reference unit, the result being subtracted from the received signal so that an error signal is formed.  The sign of the error signal is correlated with the estimated signal in a correction unit, which calculates a correction to be added to the reference signal in order to correct it. The sign of the error signal is also added to the estimated signal thereby forming said control signal which is corre-lated with the data vector in the correction unit.  This unit calculates a correction value which is supplied to the input of the balance filter for correction of the filter parameters.

Abstract: ABSTRACT: "Output amplifier for transmitting tube".     The invention relates to an output amplifier for a transmitting tube, more specifically a transmitting tetrode having an operating frequency located in the FM-and the VHF- frequency bands. In order to match the output impedance of the preamplifier to the input impedance of the output amplifier the output amplifier must comprise a broad-band impedance transformer. The conventional solution, the use of .lambda. /4  coaxial conductors arranged in air, has the drawback that this implies the use of a bulky transformer. In accordance with the invention, mechanical and electrical flexibility is obtained by using impedance transformers formed from series/parallel arrangements of coaxial cables, so that the impedance transformer needs little room and nevertheless realizes a match of a highly broadband nature.

The mill includes a main roller and at least two secondary rollers, each secondary roller opposing a different axial portion of the main roller circumference and thereby defining axially separate mill sections.  Each secondary roller is independently adjustable towards and away from the main roller.  A chain and sprocket arrangement gangs the adjustment means for opposite ends of each secondary roller to ensure that the rollers remain parallel when adjusted.  Pressure springs urge the secondary rollers toward their adjusted positions, but allow movement away from the main roller when the spring pressure is overcome.  A chain drive is employed which includes movable idler sprockets arranged so as to maintain relatively constant chain tension when the roller positions are adjusted.
